1943 Tehran Conference

The 1943 Tehran Conference was a meeting during World War II where Allied leaders—Franklin D. Roosevelt (USA), Winston Churchill (UK), and Joseph Stalin (USSR)—gathered in Iran to plan their military strategy against the Axis powers. They discussed opening a second front in Western Europe, coordinated efforts to defeat Nazi Germany and Japan, and collaborated on post-war arrangements. The conference helped strengthen the alliance and set the stage for major campaigns in Europe and the Pacific. It was a pivotal moment in coordinating Allied efforts to defeat the Axis and shaping the post-war world order.
